1 Claim. 1

This invention relates to a disposable drinking cup and it is oneobjectief the. invention to provide a cup which is formed of paper,cardboard, or the like, the bottom and the. walls of the cup beingcovered with thin metal foil which serves to water proof the materialtrom which. the. cup is formed and also prevent the flavor of liquidpoured into the cup from being impaired.

Another objectief lthe invention vis to provide a paper cup which has abody or annular wall formed from a paper blank having one surfacecovered with metal foil except rone end portion, lthereby allowing thebare end portion of the paper sheet to be adheringly secured inoverlapping engagement with the other end portion of the sheet andfirmly hold the ends of the blank together and form an annular wall forthe cup.

Another object of the invention is to provide the cup with a handle somounted that it may be disposed in a flattened position when the cup ismade and drawn outwardly to an extended position when the cup is to belled and held in a persons hand.

Another object of the invention is to provide a disposable paper cupwhich is simple in construction and may be manufactured at low cost.

The invention is illustrated in the accompanying drawings wherein:

Fig. 1 is a view of the blank from which the paper portion or annularwall of the cup is formed.

Fig. 2 is a sectional view taken vertically through the cup.

Fig. 3 is a sectional view taken transversely through the cup.

This improved cup has a body or annular wall l and a bottom 2. The bodytapers towards its lower end so that the bottom ts tightly in the lowerportion of the body, and upon referring to Figure 2 it will be seen thatthe bottom has its marginal portion bent downwardly to form a dependingange 3. This fiange has close iitting contacting engagement with theannular wall or body and the lower end portion of the body is bentinwardly :and upwardly to form a ange or circumferentially extending lip4 which overlaps the ange 3 and bears against the under surface of thebottom 2 and supports the bottom as well as forming a water tight pointbetween the bottom and the annular wall l.

The annular wall or body is formed from the blank 5 shown in Figure 1.This blank may be formed of paper, cardboard, or other suitablematerial, and is arcuate longitudinally and its end edges are cutdiagonally so that they extend downwardly in converging relation to eachother; Therefore when oney end portion of the blankV is secured inoverlapping engagement to VtheA other end portion of the blank the bodyor annular wall formed thereby will taper towards its lower endl. Thesuracefof theA blank or sheet 5 which is presented upwardly in Figureland forms the inner surface of the body i has appliedv toit a covering 5formed of metal foil whichl is preferably glued to the paper sheet. Thiscovering or lining extends the full distance betweenupper and loweredges of the blank and has one end overlapping the edge of thecorresponding end of the sheet, as shown at 6' in Figure 3, and itsother end disposed in inwardly spaced relation to the corresponding endof the sheet. Therefore one end portion 5 of the paper sheet is bare andthis end portion may be very tightly glued in face to face engagementwith the end portion of the outer surface of the paper sheet which itoverlaps. This is clearly shown in Figure 3, and referring to thisfigure it will be seen that the portion 6 of the metal foil forms awater tight seal and very effectively prevents hot or cold liquid pouredinto the cup from flowing or seeping through a crevice between theoverlapped endv portions of the sheet forming the body or annular wall.The paper disk forming the bottom has its upper surface covered with asheet of metal foil 'l and as its marginal portions which are turneddownwardly with the portion of the bottom forming the flange 3 has faceto face contacting engagement with the metal foil lining for the annularwall or body l a water tight seal is formed between the bottom and thewall. The upper edge portion of the wall or body is rolled outwardly anddownwardly to form a bead or rolled lip 8 providing a smooth marginaledge for the cup.

In order that the cup may be held while it is being used there has beenprovided a handle 9 which is formed from a strip of paper of an evenwidth throughout its length except at its ends which are enlarged toform heads I0. The heads are triangular with their wide ends disposed attheir junction with the main portion of the handle-forming strip, thusforming shoulders Il at opposite sides of the inner ends of the heads. Aslit I2 is formed in the bare end portion 5 of the blank from which thebody is formed. This slit is substantially U-shaped and has arms I3 atits upper and lower ends which extend transversely of the bare endportion of the blank and together with the longitudinally extendingportion of the slit form a tongue I4 under which the handle-formingstrip is tted. The handle extends vertically with its end portionsprojecting from upper and lower ends of the tongue I4 and is initiallydisposed in the attened condition shown in Figure 1. When the cup is tobe used the portion of the handle-forming strip exposed outwardly of thecup is grasped and pull exerted until the heads stop its outwardmovement, thus forming a semi-circular handle, as shown in Figure 2, thehandle being of such size that it may be readily grasped and the cupheld in a persons hand.

Having thus described the invention, what is claimed is:

A disposable drinking cup comprising an annular wall consisting of asheet of paper having one end portion overlapping the outer surface ofend portion of wall-forming sheets and transversely overlapped for itsfull width by said tongue and having end portions extending beyond upperand lower ends of said tongue into space between the said end portionsof the sheet and terminating in widened ends constituting heads havingbase portions projecting from opposite side edges of the strip under thesaid overlapping end of said sheet for engaging upper and lower ends ofsaid tongue and holding the strip in engagement with the wall, saidstrip being slidable longitudinally through the laterally extending endportions of the slit whereby the intermediate portion of the strip maybe drawn outwardly and form an outstanding U-shaped handle anchored y atits ends by the heads of the strip.

the other end portion of the sheet, the overlapping end portion of thesheet being adheringly secured :dat against the confronting surface ofthe overlapped end portion of the sheet, a bottom for the cup havingmarginal portions secured to lower portions of the annular wall, theoverlapping end portion of said sheet being formed with a verticallyextending slit and transverse slits extending from upper and lower endsof the vertical slit and together therewith forming a tongue free alongone side edge and across upper and lower ends and along its other sidebeing integral with the said overlapping end portion of the said sheet,and an initially flat strip extending vertically along the outer surfaceof the overlapping JACK K.
